OREAS 175 Mn (41.04 wt.%) manganiferous sedimentary

Item: OR175_10g

Unit of measure: ea

Description:

OREAS 175 has been prepared from manganese ores sourced from the Glosam Mine situated within Postmasburg Manganese Field located in the Northern Cape Province of South Africa. The ores are composed mainly of braunite group minerals including braunite (3Mn2O3.MnSiO3), partridgeite (Mn2O3) and bixbyite (Mn,Fe)2O3.

Fifteen laboratories participated in the program employing the following methods:

Mn ore package for Al2O3, BaO, CaO, Cr2O3, Fe2O3, K2O, MgO, MnO, Na2O, P2O5, S, SiO2, TiO2 & V2O5 by borate fusion with XRF finish;
Thermogravimetry: Loss on Ignition (LOI) at 1000°C;
4-acid digestion for full suite elemental package by ICP-OES and MS finish;
Specific gravity by gas/liquid pycnometry or volumetric flask.
